Tetracycline-controlled transcriptional activation - pedia Overview The T-REx System is a tetracycline-regulated mammalian expression system that uses regulatory elements from the E. Other systems such as the T-REx system by Life. to each TetO2 sequences in the absence of tetracycline. Introduction.

Tetracycline expression system - IBA While overexpressing a gene of interest can provide a look into its role in a cell, sometimes it is necessary to control the expression of a gene. PASG-IBA vectors work with the thtly regulated tetracycline tet promoter. This system uses the T7 promoter and T7 RNA polymerase for hh-level.
